The Enchondroma is a benign cartilage forming harmartoma arising chiefly from short tubular bones on hands and feet. If on a long tubular bone or flat bone such as femur or ilium, it is most likely to be a true neoplasm such as chondrosarcoma, not a harmartoma. A case of enchondroma was reported. It occurred over right ischium of 19 years old male and was found incidentally by roentgenogram. The lesion was biopsied and diagnos's was confirmed by histologic examination. It was treated by curretage with filling of cavity with bone chips. Post operative-course was uneventful.

Decreased sensitivity of N. gonorrhoeae to many existing antibiotics and the emergence and increase of penicillinase producing and of spectinomycin resistant N. gonorrhoeae necessitate intensive efforts to study on resistance. Male patients with uncomplicated gonococcal urethritis treated during the year 1990 at the VD clinic of Choong-ku Public Health Center in Seoul were included in this study. A total of 85 strains, 44 strains of non-PPNG and 41 strains of PPNG isolated from the patients were studied to evaluate their sensitivities to ampicillin, penicillin, cefoxitin, kanamycin, tetracycline, erythromycin, spectinomycin and cotrimazole. The results are summerized as follw: In non-PPNG strains, the range of MICs. MIC50 and MIC90 for both ampicillin and penicillin were 0.125-32, 2 and 16 mcg/ml respectively. For cefoxitin, they were 0.125-8, s and 16 mcg/ml respectively, and for kanamycin, 8--<64, 32 and 64 mcg/ml, respectively. For tetracycline, they were 1-64, 8 and 32 mcg/ml, while for erythromycin, 0.06-16, 2 and 8 mcg/ml respectively. For spectinomycin, they were 4--<64, 32 and 64 mcg/ml and for cotrimazole, 5--<160, 40 and 160 mcg/ml respectively. In the case of PPNG, the range of MICS, MIC50 and MIC90 for ampicillin were 8--<128, 32 and 128 mcg/ml respectively but for penicillin, 8--<128, 64 and 128 mcg/ml respectively. And for cefoxitin, they were 0.5-32, 4 and 16 mcg/ml while for kanamycin, 16--<64, 64 and >64 mcg/ml respectively. For tetracycline, the values were 2-64, 16 and 32 mcg/ml, and for erythromycin, they were 0.5-16, 4 and 8 mcg/ml respectively. for spectinomycin, they were 8--<64, 32, and 64 mcg/ml and finally for cotrimazole, 5--<160, 80 and 160 mcg/ml respectively. From these results, it is concluded that the MICs of both PPNG and non-PPNG were about 2 folds higher than the results of sensitivity tests at the same instituition in 1985. 2) The prevalence of PPNG among 35 gonorrhoeae patients who received treatment before the visit was 60% (21/35), while that among the patients without previous treatment was 40% (20/50). 3) In the cases of ampicillin, penicillin and cotrimazole, their MIC values were found to be significantly higher for the strains isolated from the patients with previous treatment history than those without previous treatment (p<0.05). 4) In non-PPNG strains, a significant positive correlation is found between the sensitivities to most pairs of ampicillin, penicillin, cefoxitin, kanamycin, tetracycline, erythromycin and spectinomycin. However this excludes some pairs such as : tetracycline-cefoxitin, erythromycin-penicillin, erythromycin-cefoxitin, spectinomycin-penicillin, and spectinomycincefoxitin (p<0.05). 5) In PPNG strains, a significant positive correlation is also found between the sensitivities to most pairs of ampicillin, penicillin, cefoxitin, tetracycline, erythromycin and spectinomycin. However, the exceptional cases include tetracycline-cefoxitin, erythromyoinpenicillin, erythromycin-cefoxitin, spectinomycin-penicillin, and spectinomycin-cefoxitin pairs. In addition, the sensitivity to kanamycin was found to be strongly correlated with that to tetracycline, erytheromycin and spectinomycin (p<0.05). Therefore it is essential for the management fo gonorrhoeae, together with a correct diagnosis, to use currently most effective treatment regimens which would also prevent the emergence of resistant strains. It is also suggested that when a treatment is failed, to use the durg which do not show correlation in sensitivities on re-treatment.

Pulmonary vein velocities have recently been estimated in conjunction with mitral flow velocities to increase our understanding o ventricular filling. The advent of transesophageal echocardiography with pulsed Doppler imaging capability has provided a method by which both the mitral valve and pulmonary vein velocities can be easily recorded because of the posterior approach providing unimpeded interrogation of cardiac structures. The purpose of this present study was to evaluate the normal pulmonary venous, mitral and aortic flow pattern by transthoracic echocardiography in neonate according to the postnatal age. The results were as follows. 1) With regard to the aortic flow, the early systolic was of pulmonary flow peaked after the onset of aortic flow and the late systolic wave occured consistently before aortic valve closure. 2) The peak velocities of early systolic, late systolic, late systolic, diastolic and atrial systolic in the pulmonary venous flow were 36.4 (13.2cm/sec, 45.3 (15.3cm/sec, 48.5 (14.1cm/sec and 16.6( 5.7cm/sec at 1 day old. the difference according to the postnatal age was not significant. 3) The ratio of peak systolic to peak distolic velocity of pulmonary venous flow was 1.0( 0.3 at 1 day o1, 1.1( 0.4 at 1 week old and 1.2 (0.3 at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). 4) The peak early diastolic velocity of mitral flow was 51.3 (15.2cm/sec at 1 day old, 54.7( 13.7cm/sec at 1 week old and 80.7 (16.6cm/sec at 1 month old. The difference between 1 week old and 1month old was statistically significant(p<0.01). 5) The peak late diastolic velocity of mitral flow was 48.3 (14.6cm/sec at 1 day old, 50.1( 9.9cm/sec at 1 week old and 71.8 (16.6cm/sec at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 6) The ratio of peak mitral early diastolic to peak late diastolic velocity was 1.1( 0.2 at 1 day old, 1.1( 0.3 at 1 week old and 1.2( 0.7at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 7) The peak aortic valve flow velocity was 62.1 (14.2cm/sec at 1 day old, 67.8 13.4cm/sec at 1 week old and 76.6 14.1cm/sec at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). In conclusion, improvement of left ventricular diastolic function was noted at 1 month old by echocardiography. These normal data will be useful in comprisons with the data, which obtained in newborn with various congenital heart disease that affects flow dynamics.

PURPOSE: Endothelin-1(ET-1) is a potent vasoconstrictor peptide. It has potent contractile and proliferative effects on vascular smooth muscle cells. Congenital heart diseases are often accompanied by pulmonary hypertension, and the severity of pulmonary hypertension is important in the prognosis. The aim of this study was to elucidate changes of ET-1 after pulmonary venous stenosis in a dog model, and investigate the interaction between pulmonary venous pressure and ET-1. METHODS: Plasma ET-1 levels were measured by radioimmuno-assay at the thoracic aorta, left pulmonary artery and left pulmonary vein. Pressures were also monitored at the same sites. Immunohistochemical staining of ET-1 was performed in the lung tissue. RESULTS: Increased serum ET-1 levels were noted at 1 hour after left pulmonary vein stenosis in the left pulmonary vein and aorta, and at 2 days after stenosis in the left pulmonary artery. Left pulmonary venous pressure was significantly increased at 1 hour after pulmonary vein stenosis, and systolic pulmonary artery pressure at 2 days after stenosis. Increased expression of ET-1 was noted by immunohistochemical staining at the lung tissue at 7 days after stenosis of left pulmonary vein. CONCLUSION: Increased serum ET-1 level and expression of ET-1 in immunohistochemical staining at lung tissue were noted after stenosis of pulmonary vein. Serum ET-1 level would be useful in the diagnosis and prediction of pulmonary artery hypertension. (J Korean Pediatr Soc 2000;43:769 778)

The origin of the stromal cell of cerebellar hemangioblastoma has long been studied electron microscopically and immunohistochemically. The results and theories about the stromal cell origin are variable and plentiful. However, the exact origin of the stromal cell remains controversial. The present study is aimed to elucidate the nature of the stromal cell of cerebellar hemangioblastoma. Ten cases of hemangioblastoma in Severance Hospital were used for immunohistochemical analysis of the stromal cell. The immunohistochemical staining of GFAP, S-100 protein, NSE, alpha-l-antichymottypsin, cytokeratin, CD 68, factor VIII related antigen, and synaptophysin were performed. The results were as follows; GFAP and S-100 protein were stained mainly but weakly in bellar capillary spindle cell and cellular process. NSE was stained mainly in foam cells, and 6 cases among them revealed strong reaction. ct-l-antichymotrypsin was stained in a few foam cells of 5 cases. Cytokeratin, CD 68, factor VIII related antigen, and synaptophysin showed negative reaction. Based on these results, it is considered that the origin of the stromal cell is histiocytic or neurogenic rather than glial. The weak positivity of GFAP and S-100 protein may support the neurogeriic origin but ct-l-antichymotrypsin positivity does not support the possibility. The positivity of GAP and S-100 protein supports the phagocytic action of histiocytic cell and suggests histiocytic origin rather than neurogenic.

A 35 year old woman, gravid 5, multiparous, was admitted to our department at 6 weeks and 5 days of gestation after being diagnosed with cervical pregnancy. Before the evacuation, the uterine arteries were embolized using angiographic techniques. As a result, dilatation and curettage were performed with minimal hemorrhage. We report one case of cervical pregnancy managed, successfully with preoperative uterine artery embolization and evacuation.
